анонимРешение задачи:1. Пусть x - начальное число;2. Это число увеличили на 20 %. Найдём это: 20 % = 0,2; 0,2 * x = 0,2x;3. Прибавим к начальному числу то что получилось: х + 0,2х = 1,2х;4. Полученный результат ещё раз увеличили на 20 %: 0,2 * 1,2х + 1,2х = 1,44х;1,44х - итоговое число.5. 1,44х > х, значит число увеличилось.
